摘　　要：为研究地震作用下轻钢龙骨注浆复合墙板-钢框架结构的受力特性和破坏机理,利用ABAQUS有限元分析软件建立了轻钢龙骨注浆复合墙板-钢框架结构的有限元分析模型,并通过试验验证了有限元分析模型的准确性。分析了钢材屈服强度、填料强度、面板类型、钢带数量以及龙骨立柱间距对轻钢龙骨注浆复合墙板-钢框架结构抗震性能的影响。研究结果表明:钢框架的钢材强度、面板类型和钢带数量是影响轻钢龙骨注浆复合墙板-钢框架结构抗剪承载力的主要因素,轻钢龙骨的钢材强度、填料强度和龙骨立柱间距对轻钢龙骨注浆复合墙板-钢框架结构的影响较小。研究成果将为此类结构在设计与施工应用中提供科学依据。In order to study the mechanical behavior and failure mechanism of steel frames embedded with light steel-framed grouting(LSFG)composite wall under earthquake,a finite element model is built by using the finite element software ABAQUS. Some experimental results are used to verify the accuracy of the finite element model. Also,the effects of steel strength,filling material strength,sheathing type,steel strip number,and stud spacing on the seismic behavior of the steel frames embedded with LSFG composite wall are analyzed. The results show that the strength of steel frame,sheathing type and the strip number have a significant influence on the shear capacity of steel frames with LSFG composite wall. However,the strength of CFS framing,filling material strength and wall stud spacing have little influence on the shear capacity of steel frames with LSFG composite wall. The research results may provide a reference for the design and construction application of such structures.
